5 v - 30 v delay relay timer โมดูลสวิทช์ไมโคร usb สามารถปรับได้ 5V-30V Delay Relay Timer Module Trigger Delay Switch Micro USB Power Adjustable Relay Module

5V-30V Delay Relay Timer Module Trigger Delay Switch Micro USB Power Adjustable Relay Module Module Highlights: Time can be adjusted via a potentiometer, meeting your most occasions MicroUSB 5.0V power supply with input, easy to use 5--30V wide supply voltage External triggering and onboard buttons Two triggering methods With a relay pull-in indicator Interference ability, under various interference will not malfunction relay for industrial control. Module features: 1. Working voltage: Wide-voltage 5--30V between any voltage, MicroUSB power connector and two solder terminals 2. Operating mode: to the module power output of the module state: normally open (NO) and the common terminal (COM) open, normally closed (NC) and the common terminal (COM) is turned on. Originating outside the contact (TRIG) to a low pulse signal, or touch trigger button and instantly, the relay and, working lights, this time, the status of the relay output: normally open (NO) and the common terminal (COM) is turned on, Normally Closed (NC) and the common terminal (COM) is disconnected after 0-24 seconds (this time can be adjusted according to your needs) relay opens after the bell, then relay back to the state before the trigger. 3. The time can be adjusted via a potentiometer, default 0-24 seconds. If you need more time, more replaceable capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example: 1M resistor capacitor 22uf then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds. 4. With a relay indicator. 5. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (direct current) following loads. 6. Has freewheeling protection relay. 7. signal terminal block is designed with a pull and a filter circuit, anti-jamming capability, suitable for industrial control. Many manufacturers have added optocoupler isolation, but with the trigger signal to the module and not isolation, would not achieve the interference effect. After the test was found to trigger or enhance the stability of end to interference, regardless of this module is the electromagnetic interference environment, or instantly through power module, the relay will not malfunction. 8. Size: 5.4 * 1.9 * 1.8cm (L * W * H) 9. Weight: 16g Applications: 1. Anti-theft alarm delay, building sound and light control light switch, etc. 2. On-time delay of on-board equipment prevents excessive current from burning the vehicle equipment when the vehicle is on fire. 3. Sequential start-up is required to prevent multiple devices from starting at the same time when the current is too large to burn down the appliance. Before purchase: 1.
